Nursing Process Final Exam Questions

Correct Answer: D

Rationale: The correct answer is D, the Western blot test with ELISA. First, ELISA is used as a screening test for HIV antibodies. If positive, a confirmatory test like Western blot is needed to detect specific antibodies. Western blot is highly specific and confirms the presence of HIV antibodies. E-rosette immunofluorescence is not typically used for HIV diagnosis. Quantification of T-lymphocytes is used to monitor disease progression in HIV but does not confirm HIV infection. ELISA alone is not confirmatory; it needs to be followed by a more specific test like Western blot.

Correct Answer: A

Rationale: The correct answer is A because pursed lip breathing helps to slow down and control the exhalation process, allowing the individual to exhale a smaller volume of air with more force. This helps to prevent air trapping in the lungs, improve oxygen exchange, and reduce shortness of breath. B: Incorrect - Pursed lip breathing does not increase expiration but rather controls it. C: Incorrect - While pursed lip breathing can promote deep breathing and better oxygen exchange, its primary purpose is to regulate exhalation volume. D: Incorrect - Pursed lip breathing does not specifically target the upper thorax but rather facilitates a more efficient breathing pattern by reducing air trapping in the lungs.

Correct Answer: B

Rationale: The correct answer is B: Ask the patient to return to the room, so the nurse can inspect the abdomen. Rationale: 1. Patient safety: By examining the patient's abdomen, the nurse can assess for any signs of distress or potential medical issues. 2. Patient-centered care: It is essential to prioritize the patient's well-being by addressing their concerns promptly and appropriately. 3. Professional responsibility: Nurses are trained to assess and evaluate patient symptoms to provide necessary care and support. Summary: A: Requesting the family to leave does not address the patient's symptoms and may disrupt the patient's support system. C: Asking about bowel movements and offering food may not be appropriate if the patient is experiencing stomach discomfort. D: Offering food without proper assessment may worsen the patient's condition and is not recommended before a proper evaluation.

Correct Answer: B

Rationale: The correct answer is B: 7 to 14 days. Marrow suppression from floxuridine typically occurs 1-2 weeks after administration due to its effects on rapidly dividing cells in the bone marrow. This is known as the nadir period. Choices A, C, and D are incorrect because 24 hours is too soon for noticeable effects, 2 to 4 days is too short for the nadir period, and 21 to 28 days is too long for the onset of marrow suppression. The correct choice aligns with the expected timeframe for floxuridine's impact on bone marrow function.

Correct Answer: D

Rationale: The correct answer is D: Hyperosmolar solutions used primarily to reverse negative nitrogen balance. Rationale: 1. Hyperalimentation solutions are designed to provide essential nutrients intravenously. 2. Hyperosmolar solutions have a higher osmolarity compared to body fluids, providing concentrated nutrition. 3. Negative nitrogen balance occurs when the body breaks down more protein than it synthesizes, requiring additional protein intake. 4. Hyperosmolar solutions can provide adequate protein and nutrients to reverse negative nitrogen balance. Summary: A: Hypotonic solutions do not increase osmotic pressure, but rather decrease it. B: Hypertonic solutions are not primarily used for hydration in this context. C: Alkalizing solutions are not the primary purpose of hyperalimentation and do not directly address cellular sweating.
